Definitions

  • the present invention relates to a method of manufacturing a glass panel including a pair of glass sheets disposed in opposition to each other with a gap formed there between, peripheral edges of the two glass sheets being bonded with low temperature melting glass for sealing the gap.
  • a method according to the preamble of claim 1 is known e.g. from US-A-2 032 003 .
  • the low temperature melting glass is often used for sealing the gap of such glass panel as above because it has superior adhesive property to e.g. metal solder.
  • the low temperature melting glass in the form of paste would be applied to the peripheral edges of the two glass sheets and heated to 480°C or higher, thereby to render the low temperature melting glass into melted state. Then, it would be cooled to the normal temperature for solidification, whereby the peripheral edges of the glass sheets were bonded for sealing the gap.
  • an adjacent face 4b of the low temperature melting glass 4 adjacent the gap V is formed as a concave face with its center portion between the glass sheets 1, 2 extending away from the gap V.
  • the glass would be cooled and hardened directly under such condition.
  • the adjacent face 4b of the low temperature melting glass 4 adjacent the gap V is formed as a concave face with its center portion between the glass sheets 1, 2 extending away from the gap V.
  • the conventional glass panel has a shortcoming in the strength of the low temperature melting glass used for bonding and sealing the peripheral edges of the two glass sheets. This shortcoming would appear especially conspicuously with a vacuum double glazing with the gap between the opposed glass sheets being maintained under a depressurized state.
  • EP 1 403 225 (a prior art according to Art. 54(3) EPC) a method for manufacturing a glass panel is disclosed with the steps of executing a joining process for joining a pair of glass plates opposed to each other and executing a baking process for suctioning gas from a void which distance is defined by spacers between the two glass sheets.
  • the present invention addresses to such shortcoming of the convention and its object is to provide a method of manufacturing a glass panel which even when constructed as a vacuum double glazing, can effectively prevent damage in the low temperature melting glass portion thereof by improving the strength of the low temperature melting glass used at the peripheral edges of the two glass sheets.
  • a method of manufacturing a glass panel having the features of claim 1 is provided.
  • a preferred embodiment of the invention is defined in the dependent claim.
  • a method of manufacturing a glass panel including a pair of glass sheets opposed to each other across a gap and joined with each other through low temperature melting glass at peripheries thereof to seal said gap comprising the steps of (a) forming a suction bore in either one of said pair of glass sheets and placing the low temperature melting glass, spacers and one glass sheet of said pair of glass sheets on the other glass sheet of said pair of glass sheets; (b) executing a joining process by heating said pair of glass sheets having said low temperature melting glass applied thereto to melt said low temperature melting glass and by joining the peripheries of said pair of glass sheets through the low temperature melting glass in a melted condition thereby to seal said gap; (c) pressing said peripheries of said pair of glass sheets to bring them close to each other as said low temperature melting glass is in the melted condition, to allow adjacent faces of the low temperature glass facing the gap to progressively bulge into the gap toward central regions of the glass sheets; and (d) cooling said low temperature melting glass with said pressing
  • the characterizing features of a glass panel thus formed are as follows.
  • a glass panel as illustrated in Fig. 3 and Figs. 5-7 , includes a pair of glass sheets 1, 2 disposed in opposition to each other via a gap V therebetween, peripheral edges of the two glass sheets 1, 2 being bonded with low temperature melting glass 4 for sealing the gap V, wherein in a cross section substantially normal to faces of the two glass sheets, 1,2, an adjacent face 4a of the low temperature melting glass 4 adjacent the gap V has a center portion thereof between the two glass sheets 1, 2 bulging toward the gap V.
  • the adjacent face of the low temperature melting glass adjacent the gap has a center portion thereof between the two glass sheets bulging toward the gap.
  • the adjacent face 4a is formed as a curved face bulging toward the gap V.
  • the adjacent face is formed as a curved face bulging toward the gap, compared with a construction wherein the adjacent face is formed as a face bulging toward the gap at an acute angle, the above construction can avoid stress concentration even more reliably. Hence, the strength of the low temperature melting glass at the peripheral edges of the glass sheets can be further improved.
  • spacers 3 are provided in the gap V between the pair of glass sheets 1, 2, the gap V being sealed under a depressurized state.
  • the atmospheric pressure is constantly applied to the faces of its glass sheets, thus causing problem in the strength of the low temperature melting glass.
  • the strength of the low temperature melting glass can be improved. As a result, it is possible to provide a glass panel which has the superior thermal insulation performance and also superior strength.
  • This double glazing P as shown in Fig. 1 , includes a pair of glass sheets 1,2 and a number of spacers 3 interposed between faces of the two glass sheets 1,2, so that the two glass sheets 1, 2 are disposed in opposition to each other with forming a gap V therebetween. Peripheral edges of the two glass sheets 1,2 are bonded together with a low temperature melting glass 4 which has a lower melting point than the two glass sheets 1, 2 and which also has a low gas-permeability, and the gap V between the glass sheets 1, 2 is sealed under a depressurized state.
  • a low temperature melting glass 4 which has a lower melting point than the two glass sheets 1, 2 and which also has a low gas-permeability
  • Each of the two glass sheets 1, 2 employs a transparent float glass sheet having a thickness ranging 2.65 mm to 3.2 mm. And, the gap V between the glass sheets 1, 2 is depressurized to 1.33 Pa (1.0 x 10 -2 Torr) or lower.
  • one glass sheet 1 defines an evacuation hole 5 consisting of a large-diameter hole 5a having an approximate diameter of 3 mm and a small-diameter hole 5b having an approximate diameter of 2 mm; and a glass tube 6 is inserted into the large-diameter hole 5a. Then, this glass tube 6 is fixedly bonded to the glass sheet 1 with a low temperature melting glass 7 having a lower melting point than the glass tube 6 and the glass sheet 1 and the leading free end of the glass tube 6 is sealed by means of fusing and the entire tube is covered with a cap 8.
  • the spacer 3 preferably has a cylindrical shape. And, in order to be able to withstand the atmospheric pressure acting on the two glass sheets 1, 2, the spacer is made of a material having a compression strength of: 4.9 x 10 8 Pa (5 x 10 3 kgf/cm 2 ) or higher, such as stainless steel (SUS 304) or Inconel 718.
  • this spacer when the spacer 3 has such cylindrical shape, this spacer will have dimensions of: approximate diameter of 0.3 to 1.0 mm and approximate height of 0.15 to 1.0 mm. Further, the inter-distance between adjacent spacers 3 is set to about 20 mm.
  • the glass sheet 2 not defining the evacuation hole 5 is supported substantially horizontal and on the top face of its peripheral edge, the low temperature melting glass 4 in the form of paste is applied and also the many spacers 3 are disposed with the predetermined inter-distance therebetween. Then, as shown in Fig. 5 (a) , the other glass sheet 1 is placed over them from the above.
  • the lower glass sheet 2 may have a slightly larger area so that its peripheral edge may slightly project from the peripheral edge of the upper glass sheet 1. This will be advantageous for e.g. the application of the low temperature melting glass 4.
  • the glass tube 6 is inserted into the evacuation hole 5 of the upper glass sheet 1.
  • this glass tube 6 can be inserted into only the large-diameter hole 5a of the evacuation hole 5 and has a length greater than that of the large-diameter hole 5a, the upper portion of the glass tube 6 will project from the glass sheet 1.
  • low temperature melting glass 7 having a doughnut-like shape is fitted and an evacuation sealing device 9 is placed over this assembly.
  • the evacuation sealing device 9 includes an evacuation cup 10 having a cylindrical shape with a bottom and an electric heater 11 disposed within the evacuation cup 10.
  • the device 9 further includes such components as an evacuation flexible pipe 12 communicated with the inner space of the evacuation cup 10 and an O-ring 13 for sealing relative to the top face of the glass sheet 1.
  • the two glass sheets 1, 2 are charged into and housed under substantially horizontal posture in a heating furnace 14.
  • the low temperature melting glass 4 is molten and with the low temperature melting glass 4 under this molten state, the peripheral edges of the opposed glass sheets 1, 2 are bonded together thereby to seal the gap V.
  • the adjacent face 4a of the low temperature melting glass 4 was formed into the curved face bulging toward the gap V.
  • Fig. 6 (a) in the heated softened state of the low temperature melting glass 4, as shown in Fig.
  • a pressing operation is effected for pressing at least the peripheral edges of the two glass sheets 1, 2 to be closer to each other and with maintaining this pressing, the low temperature melting glass 4 may be allowed to cool so as to cause the adjacent face 4a of the low temperature melting glass 4 to be bulged toward the gap V. Further, by using the pressing operation and the baking operation in combination, the adjacent face 4a of the low temperature melting glass 4 may be formed into the curved face bulging toward the gap V.
  • the temperature inside the heating furnace 14 is elevated to 480°C or higher for melting the low temperature melting glass 4.
  • the molten low temperature melting glass 4 has good wettability to the two glass sheets 1, 2, as shown in Fig. 5 (b) , in a cross section substantially normal to the faces of the two glass sheets 1, 2, an adjacent face 4 of the low temperature melting glass adjacent the gap V will be formed concave relative to the gap V and with the melting of this low temperature melting glass 4, the low temperature melting glass 7 about the glass tube 6 too is melted to flow into the gap between the large-diameter hole 5a and the glass tube 6.
  • the inside of the evacuation cup 10 is depressurized and also the inside of the gap V is depressurized to 1.33 Pa or lower via the glass tube 6 and the small-diameter hole 5b.
  • the low temperature melting glass 4 is under the softened state having the viscosity of 10 10 Pascal/sec. (Pa ⁇ s). Hence, in association of the depressurization of the gap V, its adjacent face 4a will be formed into a curved face bulging toward the gap V, as shown in Fig. 3 or Fig. 5 (c) .
  • the leading end of the glass tube 6 is locally heated to about 1000°C, so that the opening of this leading end of the glass tube 6 is sealed, as shown in Fig. 4
  • the cap 8 is bonded to the glass sheet 1, thereby to complete the vacuum double glazing P.
  • the adjacent face 4a of the low temperature melting glass 4 is formed as the curved face bulging toward the gap V. Therefore, even when the two glass sheets 1, 2 are subjected to a force which tends to displace the sheets closer to each other, as indicated by arrows in Fig. 7 , its stress will be dissipated toward the bulging portion, so that substantially no stress concentration will occur. Hence, in comparison with the conventional construction shown in Fig. 8 , the strength of the low temperature melting glass 4 can be improved significantly.
  • test samples of this invention's glass panel and the conventional glass panel were made to conduct a comparison experiment therebetween. The results of this experiment will be described next.
  • test glass panels were made by the following processes (a) and (b).

  • a testing form panel 16 allowing depressurization of its inside 15 was prepared and on this form panel 16, the two kinds of test samples were mounted. And, as a simulation of a wind load, the inside 15 of the form panel 16 was progressively depressurized by means of an evacuation pump to achieve a pressure difference of 0 to -20 kPa relative to the atmospheric pressure. In the course of this, the destruction condition was monitored and the pressure of the inside 15 at the very moment of start of destruction was determined.
  • the load due to the atmospheric pressure is applied substantially uniformly to the top side of the test sample, so that the test sample will be warped in an arcuate form with its lower side being formed as a convex face downwards.
  • the stress occurs not only on the faces of the glass sheets, but also on the interfaces between the sealed portion and the glass sheet at the end portions of the two glass sheets.
  • the sealed portion at the ends of the two glass sheets has structural weakness, the destruction will start earlier at the vicinity of the sealed portion than on the glass faces.
  • the sealed portion at the ends is strong, the destruction will start earlier at the glass faces. Therefore, the above-described results establish that the glass panel of the invention is superior in strength to the conventional glass panel.
  • the glass panel can be used in various applications, such as a window pane for a building or a vehicle (automobile, railway car, boat) or instruments such as a plasma display or a door or a wall of various machines such as a refrigerator, a thermal insulator, etc.
